Creating Database-Independent Applications With PEAR DB
Switch from one database to another without having to re-code your application

| Speaking Different Tongues |

If you've been working with PHP for a while, you're probably already aware of its support for a wide variety of database systems. MySQL, PostgreSQL, Oracle, SQL Server, dBase - these are just some of the databases that PHP supports, and it's precisely this extensive support that makes PHP so popular as a tool for building data-driven Web applications.

There's only one fly in the ointment. PHP provides a different set of functions to "talk" to each database, rather than a single, unified API. This means that if you ever switch from one database back-end to another, you'll usually have to rewrite all your PHP code to use new functions...a task that's guaranteed to take the sunlight out of your day.

Fortunately, PEAR has a solution to this problem. The PEAR DB class provides a database abstraction layer for RDBMS interaction, making it possible to switch from one database to another without having to re-code your application. Keep reading, and let me show you how it works.
